When I developed the Cold Start™ Yogurt method in June of 2017, I did not expect that it would become SO popular! One reason it is so popular is that it is very EASY to make. Another reason is that it TASTES so good!
I also did not anticipate all the questions that this method would bring, and putting all these questions/answers on my original Cold Start™yogurt post made it into a very long post.
If you are new to Cold Start™yogurt, please watch the video found here, then come back and see if you have any questions. This is the only place where you will find the original recipe, & complete information about Cold Start™yogurt. Enjoy!

FAQ
What is the Cold Start™ Method?I came up with the name, Cold Start™ method, and it is simply using 2 ingredients: cold ultra pasteurized milk & a couple tablespoons of yogurt (also called starter), mixed together and letting the Instant Pot warm up your milk automatically to the perfect temperature. No heating or cooling your milk, and no additional or special equipment is necessary. "No Boil" is not accurate to describe this method, as milk is not boiled to make yogurt.
In the Traditional Boil Method, milk is heated to 160°-180°F using the "Boil" setting of the Instant Pot to make yogurt. Milk is then cooled to 100°F -110°F, starter is added, and incubated. Incubate means keeping the milk warm, at a constant temperature of 100°F-110°F.
What if I don't have a Yogurt button?
You can still make yogurt; it will require a couple of extra steps to heat the milk and find a method to maintain the temperature of your milk in the 100°F-110°F range for at least 8-10 hours. An accurate thermometer is needed. You can find additional directions for No Yogurt Button here.
What milks can I use with the Cold Start?
You can only use ULTRA PASTEURIZED milks or SHELF STABLE milks with this method. Shelf stable milks include: canned, boxed or powder milks. UHT (Ultra high temp) milks are the same as ultra pasteurized milks.
Why? Pasteurized milk is heated to 160°F, kills any harmful bacteria, but still has natural bacteria in the milk. This natural bacteria competes with the yogurt bacteria while the milk is warming up to incubation temperature. Results are thin yogurt that doesn't have very many yogurt cultures.
Ultra pasteurized milks are heated to 280°F, quickly cooled and are 99.9% bacteria free. While the milks are warming up to incubation temp, ONLY the yogurt bacteria is allowed to grow, resulting in yogurt! If you want to use any other milks to make yogurt, use the more traditional boil method.
When using Ultra Pasteurized milk, it will not be as thick as the filtered milks (Fairlife, CarbMaster, MooTopia or Natrel Lactose Free), but you can strain it to your desired consistency. Some ultra pasteurized milks need at least 10 hours incubation to set.

Instant Powdered milk is a great option to not only make yogurt, but to add to other milks for a thicker yogurt. You can adjust the powder:water ratio for a thicker milk/yogurt or you can add 1/3-1/2 cup of instant powdered milk to every 8 cups of cold milk for a thicker yogurt.
Available in whole, 2%
Use the regular, not the iron fortified |
Carnation Instant Milk Powder
Easily available and tastes great. Use it alone or in addition to milk to make a thicker yogurt. 1/3-1/2 cup of instant powdered milk added to 8 cups of cold milk will help make your yogurt thicker.
Not everyone has access to fresh milk, so dry, or powdered milks are perfect for the cold start method and you can make a concentrated milk by using half the amount of water that the recipe calls for. You can also add instant powdered milks to cold milk to help thicken your yogurt.
You may live in another country where fresh milk is not available. You may see Ultra Pasteurized, Ultra High Temp, High Temp Short Time (HTST) or Extended Shelf Life (ESL) on the package.
Do I need to use Sweetened Condensed milk?
No. You only need to use milk & a couple of tablespoons to make yogurt. Adding sweetened condensed milk is optional and is added along with the milk at the beginning. It adds sweetness, and thickens the yogurt.
You can choose ONE of the following, add it to your milk to flavor and sweeten your yogurt:
The higher the protein, the thicker the yogurt. Adding protein drinks, or "shakes" can thicken yogurt without using full fat or adding instant powdered milks. Adding 1-2 of these 11oz shakes to a fat free milk can help make a very thick yogurt while adding flavor and keeping the sugar very low.
1. Kill pathogenic (harmful) bacteria. If raw milk is used, heating it kills bacteria. The higher you heat the milk, the more bacteria is killed. Heating milk to 160°F is pasteurization.
2. Allow only yogurt bacteria to grow. Yogurt bacteria begin to grow in a 100°F-110°F environment. So milk is heated to at least this temperature to allow the yogurt bacteria to begin doing their work.
3. Change proteins. The proteins in the milk begin to change, or denature, when the milk is heated. The higher the temperature of your milk, the more the proteins will denature. This process results in a thicker, more custard-like yogurt.
Ultra pasteurized milks have already been heated to 280°F, so no pre-heating is necessary.
Can I heat my regular pasteurized milk and Cold Start it later?
No. You would have to heat your milk to at least 280°F, which can foam, scorch and burn. Heating it only to 180°F would not be enough to use it for Cold Start yogurt, for the reasons listed above. You can read more about ultra pasteurization in the next question.
Are Ultra Filtered & Ultra Pasteurized the same thing?
No. Ultra filtered milks are milks that are screened, or filtered, to separate the milk components of water, fat, sugar, lactose, etc. and are put back together. Low fat milks use a similar process. Ultra filtered milks need to use the traditional boil method and cannot use the Cold Start.
Ultra pasteurized milks are heated to 280°F, quickly cooled and are 99.9% bacteria free. These milks are suitable for the Cold Start method because they are heated for a thicker yogurt and are bacteria free.
What is Fairlife milk?
It is 100% dairy milk that filtered, using a process similar to water filteration, by using sieves, adsorption, ion exchanges and other processes, resulting in a milk that has 50% less sugar, 50% more protein, 30% more calcium and is labeled as lactose free. Fairlife milk comes from Fair Oaks Farms in Indiana. Coca Cola does not own Fairlife; it has a partnership with Fair Oaks Farms, handling the marketing and distribution. You can find a list of 74+ stores that carry Fairlife here.
Is Fairlife milk Ultra Pasteurized?
Yes, Fairlife milk is ultra pasteurized.
It doesn't say it on the carton, so I contacted Fairlife, and this is the response I received:
Can I use any Lactose free milk? How does lactose work?
Yes. Most lactose free milks are ultra pasteurized and work well. Fairlife milk is lactose free. Lactase is added to the milk to make it "lactose free.":
Here is another explanation of lactose free milk:
But wait...don't you need lactose to make yogurt?
There are two things at work when making yogurt with lactose free milk. First, the lactose free milk is treated with the lactase enzyme to break down the lactose into its component molecules, glucose and galactose, which make it easier for the bacteria to ferment. Otherwise, they do this conversion themselves, but the process is a bit slower.
Second, the ultra filtered milk is higher in protein, and the action of the bacterial fermentation creating lactic acid which then acts to coagulate the protein. More protein, easier coagulation. -Kathy Peschell
Do I have to use a non-dairy yogurt with Lactose Free milk?
No. You can still use a dairy yogurt as your starter! The lactase added to lactose free milks will help you digest any lactose that is found in your starter. If you want to use a dairy free yogurt as your starter, you can use a dairy free yogurt: Silk, SoDelicious, or try Yogurmet, a freeze dried powdered starter.
Can I use Low Fat milk?
Yes, you can use low fat or skim milk for for making yogurt with the cold start method.
Lower fat milks have a higher water content and may yield a more soft-set, pudding like yogurt. If you want a thicker yogurt, you may want to strain or add non-fat instant powdered milk your yogurt for a thicker consistency. Fairlife, Joyya and similar low fat & skim milks have more protein, which help contribute to a much thicker yogurt than other milks.
It is not necessary to use a low fat yogurt starter with these milks - you only want the starter for the live cultures. You can find out more about How to Choose a Starter, here.
Can I use Chocolate milk or a flavored milk?
Fairlife Chocolate milk, like any store bought chocolate milk, has too many additives (thickeners, sugars and other ingredients) that interfere with the culturing process. Most people using Fairlife and other chocolate milks get a thin, "pudding-like" texture, even with a 9 -10 hour culturing time. Some add sweetened condensed milk, which does help thicken a little bit, but adds sugar to an already sweet milk. The additional sugars in the milk will need at least a 10 hour culturing time, which makes a tangy or tart yogurt. For most people, this combination of chocolate + tartness is not a pleasant taste. If you want a chocolate yogurt, make a plain yogurt, and after chilling, add chocolate syrup, chocolate drink mix powder, whey protein powder or a small box of instant pudding mix.
How can I make a DAIRY FREE cold start yogurt?
If you need a dairy free option, Soy or Ripple (pea) milk work great!
TIP: Soy or pea milks need at least 12 hours incubation to thicken and will continue to thicken or "set" while chilling in the fridge. It will not be a thick Greek style yogurt, but more of a traditional yogurt consistency.
These are the only plant based milks that don't need a thickener. Ripple pea or Soy shelf stable milk (must only contain soy and water).
Easily available and tastes great. Use it alone or in addition to milk to make a thicker yogurt. 1/3-1/2 cup of instant powdered milk added to 8 cups of cold milk will help make your yogurt thicker.
You may live in another country where fresh milk is not available. You may see Ultra Pasteurized, Ultra High Temp, High Temp Short Time (HTST) or Extended Shelf Life (ESL) on the package.
Amanda Atchley, who lives in Japan, found this ESL milk. It took about 11 hours to set, which can be true of some ultra pasteurized milks. She also strained it for a thicker texture.
Here are some examples of boxed, shelf stable milks. Some people have found boxed milks at their local dollar store.

I live in Canada. What milks can I use?
You can use any UHT (ultra high temp) milk with the Cold Start. Most organic or lactose free milks are UHT. Organic milks can take longer to culture or set, as long as 10-12 hours.
Fairlife milk is now available in some parts of Canada! Joyya is the closest in composition to Fairlife milk. Natrel lactose free milk, is another popular choice. *NEW! Natrel Plus with 18 g of protein is now available!
Natrel filtered milks are NOT ultra pasteurized. Only the lactose free version is ultra pasteurized, so look for the orange label.

Can I use this method with other Ultra Pasteurized milks?
For the most part, yes. Sometimes the high heat process damages the proteins in the milk to the point that it won't set. Some UP milks take longer to incubate, up to 10 hours or more. Milks that you can try for the cold start method are: Organic milks, Soy milk, canned milks (evaporated or sweetened condensed), heavy cream, half & half, powdered milk (mixed with filtered water), any ultra pasteurized or ultra high temp milks. Organic milks can take longer to culture or set, as long as 10-12 hours.
You will need to keep in mind that Fairlife milk has more protein, which helps make a thicker yogurt. Higher fat and more protein is what makes whole milk yogurt thicker than a1% or non fat milk yogurt.
Why is milk heated to make yogurt?
Three reasons:1. Kill pathogenic (harmful) bacteria. If raw milk is used, heating it kills bacteria. The higher you heat the milk, the more bacteria is killed. Heating milk to 160°F is pasteurization.
2. Allow only yogurt bacteria to grow. Yogurt bacteria begin to grow in a 100°F-110°F environment. So milk is heated to at least this temperature to allow the yogurt bacteria to begin doing their work.

Do I have to use Fairlife Milk?
No. You can use any ultra pasteurized, ultra high temp (UHT), or shelf stable milks which include: canned, boxed or powdered milks. Many use Fairlife milk as it helps make a much thicker yogurt that doesn't need straining. This is because it has more protein than other ultra pasteurized milks.What is Fairlife milk?

Yes. Most lactose free milks are ultra pasteurized and work well. Fairlife milk is lactose free. Lactase is added to the milk to make it "lactose free.":
"Those who are lactose intolerant are not allergic to milk, or even to lactose. Instead, they lack the digestive enzyme needed to break down the lactose, or the sugar in milk.
"Lactose-free milks are the same as regular milk, except for the addition of lactase. This neutralizes the lactose and, therefore, eliminates the gastrointestinal trauma. Lactase does make milk taste sweeter. Also, to neutralize the lactase enzyme inactive, manufacturers ultra-pasteurize the milk, a move that extends the shelf life." - Karen Fernau, Food writer
"It’s neither practical nor really possible to remove lactose from milk — not only would it be logistically difficult, it’s simply not necessary. Instead, manufacturers react the lactose chemically, altering its composition and converting it into molecules that your digestive system processes easily. To react lactose, manufacturers add small amounts of the enzyme lactase to milk, explains OrganicMeadow.com, a producer of lactose-free milk. The lactase splits lactose into its constituent components, which are two sugars called glucose and galactose." - How is Lactose Free Milk Made?

These are the only plant based milks that don't need a thickener. Ripple pea or Soy shelf stable milk (must only contain soy and water).
Almond, Coconut, Rice and other plant based milks need a thickening agent (gelatin, agar agar, tapioca starch, etc) and those thickeners require heat to activate. These milks will not work well for the cold start method.
Does the Cold Start™ method save any time?
Yes, it can! It only takes 2-3 minutes to mix up your milks, push the yogurt incubation setting, and walk away. Most find that they don't need to strain, which saves 4-8 hours.
Is it safe to make yogurt with this method?
Yes. I have tested the temperatures of the milk in my testing and found that the Instant Pot yogurt setting warms up the milk to 107°F within 30 minutes, well within food safety guidelines. The Unsafe Food Zone temperature range is 40°F-140°F as determined by the USDA.
The Unsafe Food Zone
The unsafe food zone is any food that is left out in the temp range of 40°F-140°F for 2 hours or more. It is perfectly fine for any milk to be in the unsafe food zone as long as the yogurt starter is actively working in the milk. Once the yogurt starter is active (in the 100°-110° range), it begins to produce acidic whey, which continues to ferment and preserve your milk in this temp range. Milk without an active yogurt bacteria present should not be left out at room temperature for 2 hours or more.
UP/UHT (ultra pasteurized/ultra high temp) milk already has 99.9% of the bacteria killed during processing, meaning there is little risk, if any, of any pathogenic (bad) bacteria multiplying during the warming up to the incubation zone, as long as it is less than 2 hours. Once you open UP/UHT (ultra pasteurized/ultra high temp) milks, it needs to be treated like dairy milk. Even though UP/UHT milks are shelf stable in their sterile packaging for 6+ months, once opened, their fridge shelf life is 1-2 weeks and should not be left open at room temperature for more than 2 hours.
You should not try the Cold Start™ method with raw or regular pasteurized milk. See below.
*If you are undecided about the safety of using the Cold Start™ method, you can always warm up your yogurt to 100°-110°F, add your starter and incubate from there.
Can I use the Cold Start™ method with regular pasteurized milk?
I do not recommend using the Cold Start™ method with regular pasteurized milk. Even though the milk is heated to 160°F for pasteurization, there are still natural bacteria present in the milk. This bacteria can grow/multiply during the 30-40 minutes of warming up to incubation temp & compete with the natural bacteria in the yogurt starter. This competition of bacterial strains may result in either a thin, runny yogurt, lumpy, bitter, stringy or ropey yogurt. You can see the results of what happened with raw milk:
For raw, pasteurized & filtered milks, you can find this simple method here for thick, Greek style yogurt.
How do I sweeten or flavor the yogurt and when do I add it?
If you want a vanilla yogurt, you can add your vanilla extract when your yogurt has chilled and strained. It is theorized that the alcohol from the extract can interfere with the culturing process, but you can add vanilla bean paste or scrape a 2"vanilla bean into your milk before starting. If you are straining your yogurt, any flavor or sweetener can go out with the whey.
Sweetener, Added AFTER CHILLING:
You can use any sweetener of your choice after your yogurt has chilled and strained. Granulated sugar, powder sugar, maple syrup, or any alternative sweetener can be used. Honey mixes in better if it is warmed first. If you add sugars to your milk prior to heating, it can inhibit, or slow down the culturing process, adding time to your yogurt to properly set. I prefer to add sweetener after my yogurt has finished. You can add a small box of instant pudding, coffee, drink mix, or get some inspiration from this topic in my Instant Pot Yogurt Guide for Newbies.
Sweetened Condensed Milk, Protein Drinks, Creamers, Added to the milk BEFORE incubating:
You can add a up to small can of sweetened condensed milk to your Fairlife milk prior to heating. Make sure it is mixed in well and plan to add time if necessary to allow your yogurt to gel, or set. This makes a creamy, slightly sweet vanilla yogurt.
Can I mix the milk & starter together and pour them into individual jars first?
If you are not straining your yogurt and like the consistency, you can try it. Fairlife and other filtered milks will make a yogurt that has the thickness between Greek and traditional yogurts. You can use canning jars or Oui yogurt jars.
Yes, it can! It only takes 2-3 minutes to mix up your milks, push the yogurt incubation setting, and walk away. Most find that they don't need to strain, which saves 4-8 hours.

Sweetened Condensed Milk, Protein Drinks, Creamers, Added to the milk BEFORE incubating:
You can add a up to small can of sweetened condensed milk to your Fairlife milk prior to heating. Make sure it is mixed in well and plan to add time if necessary to allow your yogurt to gel, or set. This makes a creamy, slightly sweet vanilla yogurt.
Can I mix the milk & starter together and pour them into individual jars first?
If you are not straining your yogurt and like the consistency, you can try it. Fairlife and other filtered milks will make a yogurt that has the thickness between Greek and traditional yogurts. You can use canning jars or Oui yogurt jars.
Dry fit your jars to make sure they fit. Estimate the amount of milk you will need to use. If you have any milk mixture left over, put it in a clean container with well fitting lid and use it within 24 hours to make yogurt.
When 2 layers of jars are used, the bottom jars will set while the top layer is still liquid milk. It can take at least 10 hours to for the top layer to set. No trivet/metal rack or lids are necessary. You can add 1"-2" of water, which seem to help incubate the yogurt, but it is not required.
Does the texture change with this method?
No. If you use whole milk, it will taste creamier. You can use 2% or skim, and have it strained nice and thick, but the texture may not be as creamy. If you like the taste of the milk, you'll enjoy the yogurt made with it.
Why is my yogurt grainy or gritty?
The yogurt stuck on the bottom of the pot does have a gritty or grainy texture. Take a look at the photo, below, taken right after incubation and before straining in the fridge. Avoid scraping this into your yogurt. This may be difficult to avoid if you chill your yogurt while in the pot prior to straining.
Try slowly pouring your yogurt immediately into another bowl or your lined strainer and chill in the fridge or use the Ice Cube tip in my traditional yogurt recipe, which keeps the milk from sticking to the bottom of the pot. If you still find your yogurt to have a grainy texture, try another brand of yogurt as your starter. Each brand of yogurt has a unique blend of bacterial strains that make up both the tang & texture of your yogurt.

The yogurt stuck to the bottom of the pot had a grainy, gritty texture. When using the ice cubes, this is how my pot looked after milk was heated. |
I made the cold start yogurt 3 times and it turned out great! Made it as your instructions, with the sweetened condensed milk. Didn't make it for months and now tried it 2 times and it never set. Used exactly the same ingredients and it did not set, don't know what I did wrong? Any suggestions?
ReplyDeleteThere are two possibilities. One, you may have had your yogurt on the Low/Less setting, or two, your starter was weak or inactive. If this happens again, check your settings and/or try adding a couple of extra hours for incubating. If that doesn't help, test the temp of your yogurt setting. This can be done by using 4 cups of water, select your yogurt incubation setting (Normal/Medium/Custom), wait 30 minutes and test the temp of the water. It should be in the 100°-110°F range. :-)
DeleteHope much does this recipe make?
ReplyDeleteIt depends on how much milk, the milk percentage, you use and if you strain it for a thicker yogurt. You can halve the recipe, or double it if you wish. You can find the complete recipe here. :-)

I have a pretty new IP and have only made yogurt about 4 times. The first 2 times I used fat free Fairlife milk with yogurt I bought. The last time I used Fairlife fat free milk and used yogurt I had frozen from my previous batch as a starter and it came out fine. Today I used Simply Nature Organic ultr-pasturized fat free milk with 8g of protein with more of the frozen yogurt I had saved to use as a starter and after 8 hours I ended up with warm milk. Why would that happen and is there anything I can do to fix it or is it a loss? thank you
ReplyDeleteSome ultra pasteurized milks can take up to 10 hours to culture, or set. If it doesn't set up or show any signs of thickening by the 10th hour, I'd toss it. If it shows some evidence of thickening, you can use the thin yogurt in smoothies or frozen yogurt pops. You can also check my troubleshooting section of my Yogurt Guide for additional information. :-)

My FairLife whole milk bottle lists as an ingredient "lactase enzyme" even though the bottle is labeled "lactose free." And it does not mention "ultra pasteurized" even though you said they wrote to you saying that it is ultra pasteurized. I love their milk products but wonder about the integrity of their labeling.
ReplyDeleteHi David -
DeleteAll lactose free milk contains lactase. You can read in my article above how this works in milk to make it "lactose free." I, too, was confused about this. I do agree that there should be something on the label that states the milk is ultra pasteurized. That would be helpful, as folks get that confused with "ultra filtered," which is a totally different process. π
Frieda: If I use a freeze dried starter to your cold start with one container of Fairlife (red) and a can of sweetened condensed milk as per your recipe would one packet be enough? Thank you in advance
ReplyDeleteCheck the directions on the box. The brand I'm familiar with uses one 5g packet with every liter or quart of milk.π
DeleteI want to make the frozen yogurt. I read the Cherry Garcia recipe. The question I have is: do I need to strain the yogurt or can I use it the way it is after the 4-6 hours in the refrigerator. I am doing the cold start method with the condensed milk, 1% Fairlife, and 0% Fage for the starter.
ReplyDeleteWith 1% milk, you will want to strain it for a creamier texture. If you don't strain, the texture will be more icy and closer to a popsicle. For best results with frozen yogurt, I recommend using a full fat yogurt.
DeleteCan I freeze the yogurt I use as a starter instead of wasting the rest of the container?
ReplyDeleteAbsolutely. Freeze the tast of yout yogurt asap from opening in tablespoon portions. I like to use an ice cube tray. Transfer frozen starters to a freezer baggie and they will keep viable for up to six months.
DeleteYou can find many more answers to questions about yogurt in my Instant Pot Yogurt for Newbies Guide. π
https://www.friedalovesbread.com/2017/07/instant-pot-dairy-yogurt-for-newbies.html
Can I use the non-stick pot instead of the stainless? Can I put the milk (for cold start) in a smaller pot inside the 8 quart pot so that it won't take up as much room in my fridge? Will that effect the timing?
ReplyDeleteYou can use your ceramic insert for making yogurt. You can use PIP (pot in pot)style by putting jars or food safe bowl inside your insert. You may want to add 1"-2" of water to the insert if you use PIP. You can slowly pour your warm yogurt into s strainer or smaller container that fits in your fridge. No scooping or stirring until your yogurt has fully chilled. π
ReplyDeleteIf I use the pot in pot method, do I place the pot on a trivet with the water underneath or just set the pot in the water?
DeleteThanks. I think I will try the PIP method. I haven't made yogurt before and I am afraid of breaking up the yogurt by transferring it before it chills. If it is very thick from the start, that is if it passes the spoon test, will it pour?
ReplyDeleteMost spoon test pictures you see are after yogurt has chilled. Please watch my other video of making boil method yogurt and you can watch me pour my warm yogurt into a strainer. It will break up into large chunks, but that is ok. Stirring your warm yogurt is not ok. You'll do great!π
Deletehttps://www.friedalovesbread.com/2016/07/no-powdered-milk-pressure-cook-greek.html
After you strain the yogurt, if you transfer it to another container will it lose its consistency/thickness?
ReplyDeleteIt won't.π
DeleteI love your cold start yogurt recipe. Will never go back. Make it often. Yesterday I tried in small yogurt jars in my IP. Only the bottom ones set up. Today I did the top row for 4 more hours and they set up. Can I only do one layer at a time? Would appreciate your advice.
ReplyDeleteMost folks incubate both layers of jars for a total of 10 hours, which gives additional time for the top layer to set.
DeleteYou can incubate one layer at a time, providing you are incubating as soon as you mix the milk & starter. π
I use fairlife 1% and vanilla oui yogurt, but then need to strain it. Leaving me with a lot less yogurt. How much instant milk powder should I use to get it thicker? I sweeten after with mio drink flavors, and use some in place of sour cream.
ReplyDeleteLow fat milks have a higher water content and Fairlife will still give you a thicker yogurt than its counterparts due to its high protein. Try adding 1/3-1/2 cup instant powdered milk mixed into your cold milk to start. π
DeleteYou don't mention using the Instant Pot glass lid. Is it ok to use it since I have one? Thanks!
ReplyDeleteYou most certainly can use the Instant Pot glass lid for making yogurt. Any lid from your pots,pans, dinner plate, pie plate or silicone suction lid will work as well.π
DeleteHi Frieda! I used the cold start Message with oat milk and oat yogurt. I let it sit in me instant pot for 12 hours and refrigerated it but it's still all liquid. Can I save this anyway?
ReplyDeleteI'm sorry, but the only plant based milks you can use with my Cold Start yogurt recipe are soy or Ripple pea milks.
DeleteAll other plant based milks need a thickener (gelatin, tapioca, agar,etc) and the boil method to work. I'm not sure you can save this batch. Sorry!
Can you just stir the whey back in or do you have to strain it out?
ReplyDeleteStraining is optional and depends on how thick you like your yogurt. If you do strain,and it's too thick, you can whisk some whey back in to your desired consistency. π
DeleteI added 1 cup of powdered Carnation skim to thicken the yogurt and it did but also made it too tart for me. Did I add too much powered milk and/or if I incubated it for less than 8 hours, say 6, would that lessen the tartness? I used have 10% cream to one batch to reduce carbs and it was pretty much perfect. But then I worried about the fat. Go figure. Don't mess with success. Thanks, I love this site and your research.
ReplyDeleteHi Connie!
DeleteAdding instant powdered milk should not make your yogurt tart. Your starter and/or your incubation time is what creates tang in your yogurt. Try a yogurt that tastes mild to you as your starter or shorten your incubation time to 6-8 hours. Some ultra pasteurized milks do need at least a 10 hour incubation time, but if you use a mild starter, your yogurt can still taste mild at 10 hours.
Hi Frieda, I just got a 2nd IP with a yogurt button. Just wondering if I can use a vanilla Greek yogurt as a starter as I have some already in my fridge? It's not freshly opened .. do i need a new container? I dont even like yogurt lol but my family does��
ReplyDeleteCongratulations on your new IP! You'll love it & your family will enjoy your gift. You can use a vanilla Greek yogurt as your starter, but for a successful yogurt, you'll want to use an unopened one. Once opened, the live bacteria begin to weaken. π
DeleteHi Frieda,
ReplyDeleteThanks for all the information. I've been trying the different milks here in Canada and so far Fairlife has yielded the best result. I'm now attempting non dairy cold start yogurt with almond milk that seems to have a thickening agent. So far I've been pulling bits and pieces of information together to understand the process however do you have a page that has all the directions in/on one location for making cold start yogurt with plant based milks?
Hi - at the moment, this page is the only place that you can find information on milks for Cold Start yogurt. Soy or pea milks are the only plant based milks that I can recommend using the Cold Start method.
DeleteAlmond milk has too much water to make a thick yogurt. Homemade almond milk works better, but still needs a thickening agent (gelatin, agar, tapioca starch, etc.) & the boil method to activate the thickeners. π
Hi Frieda! I made yogurt using your cold start method yesterday for the first time. I used 1 container red fairlife with 2 tbsp vanilla oui and per suggestion from someone I added approximately 1.5 tbsp vanilla extract. Whisked well and incubated for 8 hours. Wiped the condensation and put directly in the fridge overnight. There is a film across the top that seems to peel off and everything underneath seems fine. Any ideas? Could this be due to the vanilla extract or is it normal? Thank you!
ReplyDeleteHi - Not sure what you mean by "wiped the condensation," but I just put my pot of warm yogurt directly into the fridge with a paper towel over the insert and put a dinner plate on top. I don't notice any layer or film on top of my yogurt. I don't think the vanilla extract is the cause, although I think it is more likely the lack of condensation during incubation and/or during chilling while in the fridge. I have heard about this "film" a couple of times from others and not quite sure of the cause. In the meantime, experiment with the paper towel tip, using it or not using it, and note if you are covering your pot of yogurt adequately during incubation & while chilling. If you do notice a film, you can scrape it off and enjoy the creamy yogurt underneath. π
DeleteWill your cold start method work in a yogurt maker with 8 jars?
ReplyDeleteIt depends on the type or brand of yogurt maker you use. If their recipe has you beat the milk on your stove, cool, add starter, then transfer the mixture to the yogurt maker, then yes, you can use my Cold Start yogurt recipe.π
DeleteI did it. Came out great! Thanks for the time saving recipe!
ReplyDeleteYou are most welcome! I'm glad you made this recipe and enjoy it. π
DeleteI had some mix left after filling my cups. I put that in a plastic container with lid wrapped it in a towel and put it in the oven with the light on. Also came out great. I have that straining now for greek yogurt! Kinda worked out well that we'll try both kinds on my first try.
ReplyDeleteThat's a great idea and I'm glad you tried both methods of incubating your yogurt. If there is room, you can fill additional cups and stack them on top of your other cups, off setting them. π
DeleteCan you use the Fairlife with DHA Omega3 added for your milk?
ReplyDeleteAbsolutely! You will want to taste the milk first,as some have noticed a difference in taste with this milk coated to the milk without the omega. If you like the taste of the milk, you'll enjoy the yogurt made with it.π
DeleteI have had great success with your cold start method with a bottle of natural bliss, a bottle of fairlife reduced fat milk, 2 heaping tablespoons of Mountain High vanilla yogurt and a full teaspoon of whatever flavoring extract I want to use. The alcohol in the extracts have never interfered with the yogurt coming to a wonderful thick smooth texture. I think because I am using a larger starter and there are several strains of bacteria in this starter.
ReplyDeleteHello frieda ive used your recipe several times with great results thank you for all the detail an work you put into sharing. Ive noticed alot of instant pot recipe talk about making yogurt an when people talk about adding creamer or scm they didnt mention adding more time like 10hrs instead of the 8. Should I mention it I usually suggest them to your recipe but even I just seen today the thing about 10hrs.
ReplyDeleteWhy does the yogurt seem "stringy" when I add a can of Eagle Brand milk? It goes into the boiled, temp. reduced plain ol' whole milk when I add the yogurt as culture. It is well stirred in. It never does thicken enough either, it turns out as a sort of thick drinkable, after straining. It is tasty but I want spoon-able consistency. Temperatures were spot on during prep. Everything was sterilized as well. Is the sugar in that sweet milk killing the bacteria? I'm flummoxed here, HELP!! :)
ReplyDeleteEagle or Carnation brands of scm usually do not cause yogurt to be stringy, but other store brands seem to make yogurt stringy. Sugar does NOT kill yogurt bacteria, but does slow down the incubation process. I would check your Yogurt setting, making sure you are using the correct setting for incubation.
ReplyDeleteCan I use Noosa Vanilla Bean yogurt as my starter for cold start method?
ReplyDeleteAbsolutely. :-)
DeleteCan I do cold start with my cusinart yogurt maker?
ReplyDeleteYes, you can. Just mix your ingredients and select the yogurt incubation setting. Make sure you only mix enough milk that your maker will hold. :-)
DeleteHi Frieda! I am addicted to your recipe and make it every week. Love it with frozen berries. My husband went and bought the Fairlife milk for me but he bought almond milk creamer instead of Bliss. I told him I didn't think it would work. He bought 3 of them! Should he return them?
ReplyDeleteAlmond creamer is fine to use, but will not set up quite as thick as using an all dairy creamer. :-)
DeleteThank you so much for your reply! Appreciate it!
DeleteIf I ended up on less but corrected it to normal will I need more starter or should it be okay?
ReplyDeleteThe Less setting is too low in temperature to culture yogurt properly. If you notice this within 2 hours of starting, you can change the yogurt setting to Normal. If it has been several hours, you'll need to toss it, unfortunately. Sorry!
DeleteCan I add flavoring before incubating, such as Skinny Mixes flavored syrups? Or should I flavor it after it's been refridgerated?
ReplyDeleteI just bought an Instant Pot and I'm trying to figure out how to make yogurt. Another site said that the yogurt is actually set at about 6 hours and the longer you let it intubate the tarter it becomes. She said you can taste it after 6 hours and if you like it, it's done. What is your thoughts on that?
ReplyDeleteAlso, when do you strain (if needs be) after you chill it in the fridge or immediately after removing it from the IP?
Yogurt *can* be set in as little as 6 hours, but that really depends on the starter and how active it is. Some powdered direct yogurt starters culture yogurt in a very little amount of time, about 4-6 hours.
DeleteIt also depends on the milk used. Some ultra pasteurized milks, especially Organic milks, take much longer to culture, or set.
When I use store bought starter and Fairlife milk, my yogurt is "set" or cultured by 6.5 hours. The temperature of the IP's can also vary - range from 100°-110°F. The warmer it is, the faster it will set. My IP incubates at 107°F.
After your yogurt looks set, you CAN sample it to see if it has developed the tang level you want. Do not stir. If you want more tang, you can reset your yogurt setting for another few hours.
It's done when YOU see that it has set AND has reached your desired tang level.
If your yogurt looks set, you can strain & chill it at the same time. I demo this using coffee filters in my boil method yogurt video.
I hope this answers your questions - you may want to browse through my IP Yogurt Guide for Newbies if you have any additional questions. Enjoy your yogurt! :-)
I use a container of Fairlife milk to make cold start yogurt. I noticed you had a picture of a Premier Protein shake for use when sweetening & making thicker. How much of a bottle of Premier Protein should be used / or can be used with the Fairlife Milk. Is it less than a full bottle or a lesser amount?
ReplyDeleteI would use 2 Premier Protein drinks added to 1 carton of Fairlife or 1/2 gallon of ultra pasteurized milk. I believe they are 14 oz. Increase your starter to 2 Tablespoons when adding these drinks to your base milk. :-)
DeleteIf straining yogurt, does it need to be refrigerated within a certain length of time? I got a nut milk bag to strain my yogurt but, none of them are the advertised size when I get them. So they don’t fit over many of my bowl like I planned. But I can hang it on my cabinet handle & strain it. But curious if that’s ok before I refrigerate it.
ReplyDeleteIt will need to be in the fridge within 2 hours due to food safety concerns. Chilling not only firms up your yogurt, it slows down the culturing process that produces acidic whey.
DeleteI have seen folks tie their nut milk bags to a wooden spoon and put it in a tall drink pitcher, with the spoon straddling across the top. This setup may work better in your fridge. :-)
Can you use 2 TBSP of a previous batch of Cold Start Yogurt for the starter?
ReplyDeleteYes,you can. For more information on reculturing your own yogurt, see the topic posted here in my IP Yogurt Guide for Newbies:

Hi, Frieda,
DeleteI've been using your cold method for a while now and love it no matter if I'm making non-fat (add non-fat dry milk to help thicken) or full fat. Always comes out great. My question is...if I save my whey and freeze it in ice cube trays, can I use those as starter? Are the cultures still live? If so, how long can I keep it in the freezer and how many cubes do I use for a batch,
You can freeze and save your whey to use as starters, provided they are frozen within 24 hours of making it. You'll want to store your frozen starters in a freezer ziploc baggie to ensure freshness. I cover my ice cube tray with plastic wrap while freezing and there are some ice cube trays that come with covers. It will keep for up to 6 months in the freezer. Yes, the live cultures are alive, they are in stasis (asleep) while frozen. Use the same amount of whey as you would yogurt for your starter: 1 Tablespoon for every 8 cups of milk. :-)
DeleteYour detailed yogurt explanations and hints are so helpful! I had no idea it could be so easy! I found your site from a comment on another YT IP video. I made a half-recipe of your cold start yogurt in my Instant Pot Mini (3 quart) twice this weekend, and both times it came out perfectly, much better than store-bought! I used ultra-pasteurized organic whole milk from Aldi, freshly-opened starter from full-fat Greek yogurt, and added 1/4 cup nonfat dry milk powder to encourage a thicker end result. Ten hours on the yogurt setting with a silicone lid, and then strained in the refrig through coffee filters. It came out so much more creamy, smooth, and with a better flavor than the yogurt I usually buy (and used as starter). And it's mostly organic, too, which is hard to find and quite expensive. Thank you!
ReplyDeleteWe love your cold start IP recipe. We go through a double batch every week.
ReplyDeleteHow do you calculate the nutritional values? We strain the whey out overnight (10-12 hours). We like it think π. Does straining the whey or heating the milk change the nutritional values of the milk?
I'm glad you are enjoying my Cold Start yogurt!
DeleteIf you weren't straining, you could get a close estimate on the nutritional value by entering the info into a nutritional calculator (ie.MyFitnessPal)and dividing the result by serving size.
When filtered milks are used and are strained, there isn't any information on the nutritional value of whey.... only when regular pastuerized milks are used.
Heating the milk doesn't change the nutritional value; it changes the milk proteins for a thicker result.
Straining thickens and results in yogurt that has more protein, less carbs and less calcium. π
I just attempted my second batch of yogurt using the cold start method and Ripple vanilla milk. First batch was great, but my second batch didn't turn out at all. I'm really not sure why. After 12 hours it appeared as though the milk was just starting to culture instead of being more done. Does it matter if the milk is sweetened or unsweetened? I think the first batch I made was sweetened original and the second batch I used unsweetened vanilla. I don't know if that makes a difference.
ReplyDeleteIf your yogurt is showing signs of culturing near the bottom, check your yogurt setting. It may be on Low/Less. If this is the case, you'll have to toss it out.
DeleteIf your yogurt setting is on Normal or Medium, that's the correct setting and you'll need to add more time. Either milk should work fine. However, non dairy milks can take much longer to culture, at least 12-15 hours.
If you are trying to reculture your own non dairy yogurt used as a starter, non dairy yogurt doesn't culture very well. You'll need to use fresh yogurt every time.
π
I attempted the cold start method with Ripple milk for my second batch, but it didn't turn out. My first batch was great after 12 hours and straining, but the second batch didn't culture. Does it matter which type of milk you use, sweetened vs unsweetened? Vanilla or original?
ReplyDeleteI did have it on medium setting and added more time. Even at 16 hours it was still not done. There was a tiny bit of culturing on the top and bottom. That was it. I did not use a starter from the last batch. I used straight probiotics in both batches.
ReplyDeleteThanks for the additional information. Since you used the correct milk & yogurt setting for your Ultra, your probiotics used were the culprit. They were too weak to culture your milk into yogurt.
DeleteProbiotics can be expensive and tricky to use in making yogurt. There's so many strains & strengths available. Use too much, and the yogurt is lumpy & bitter. Don't use enough or the right strains, it will be thin and curdled. Probiotics are heat sensitive and should be kept in the fridge or freezer.
I prefer to use Silk or Kite Hill non dairy yogurts as starters, as they are more reliable. Do not get the coconut flavor ones, as they do not work for some reason. π
Hi Fireda. I've been making the cold start with Fairlife milk and I love it! I'm having issues with cow's milk, unfortunately. Can this be made with dried goat or sheeps milk? I would imagine that if I found actual goat or sheep's milk I wouldn't be able to use the cold start.
ReplyDeleteYou can use soy,Ripple or Silk Blend with my Cold Start yogurt recipe, using non dairy yogurt (Silk) as your starter and at least 12-15 hours incubation.
DeleteI have a goat milk yogurt recipe on my site (look under Pressure Cooker tab), but you will need to add a thickener and use the boil method. π
We love this recipe and use it all the time. We use fairlife and natural bliss creamer. In chatting with my husband we were discussing the sugar content. We are wondering if it is better than store bought options. How do you most accurately determine the sugar content?
ReplyDeleteI'm glad you are enjoying this recipe. If you are not straining your yogurt, you can enter the nutritional values of your ingredients into MyFitnessPal or similar nutritional calculator and divide by the number of servings.
DeleteIncubation naturally reduces the sugars in yogurt; the longer you incubate, the more tang and less lactose (milk sugars). Straining yogurt reduces sugar and you can choose to omit the creamer and add natural or alternative sweeteners to your serving of chilled yogurt. Unfortunately, there's no accurate way to measure the sugars when straining or increasing incubation time. 15-24 hours renders your yogurt lactose free, but very tangy. π
Hello. How much Natural Bliss do I use with one bottle of Fairlife milk? Thank you.
ReplyDeleteYou can use up to 16oz of Bliss creamer. You can find the printable recipe here or as a link at the top of the page:
DeleteOriginal Cold Start Yogurt
https://www.friedalovesbread.com/2017/06/easy-cold-start-yogurt-no-boil-method.html
I have been using a Euro Cuisine yogurt maker to make my cold-process yogurt for over two years now. My ingredients are Fairlife Ultra-filtered whole milk, Aldi brand Delightfully Pure vanilla creamer for taste, and 3 rounded tablespoons of Chobani plain Greek yogurt for starter. It has always been just what I want. I like a nice firm, not creamy consistency. However, here lately the yogurt has been turning out way too creamy. Nothing in my process has changed. I always go 10 hours on the yogurt maker. The yogurt maker runs at 120-125 degrees.
ReplyDeleteBased on seven 5 ounce cups, my ratio is as follows:
8 ounces of vanilla flavored creamer;
3+ tablespoons Greek yogurt;
27 ounces Fairlife whole milk.
I think the problem may be that the creamer formula may have changed and has less protein. I'm going to try using Fairlife 30g vanilla protein shake for flavor and more protein.
Do you think that the above ratios will work or should they be adjusted?
Creamy texture has more to do with the fat content of the milk. Also, you really only need 1-2 tablespoons of active yogurt starter for every 8 cups of milk.
Delete2 tablespoons if creamer is added.
120°F is too warm for incubating yogurt & can kill your yogurt cultures. A beter temp range is 100°-110°F. Less protein in the milk or creamer will result in less firm yogurt. π

I must have made yogurt using your recipes at least 100 times and have never had a fail. For at least 3 years I've used Fairlife but the price is going up so I returned to your site and was delighted to find so much more information. You really are a yogurt scientist! Thank you so much!
ReplyDeleteDo we have to start with 8 cups which makes a lot of yogurt. Or could I use 4 cups and only a half tablespoon of yogurt? If I have to use 8, how long can I freeze leftovers? Mason jars? Thanks so much!
ReplyDeleteYou can halve the recipe using 4 cups of milk and a half tablespoon of yogurt starter. Homemade yogurt will keep for up to two weeks in the fridge. π
DeleteHi, first of all I love this recipe, I always recommend it to anyone who asks. I was wondering I have a carton of unopened fairlife. It's getting close to it's best by date. Is it OK to use for yogurt. I know that's a sell by date and not necessarily go bad date.
ReplyDeleteThanks
Thanks for taking the time to ask an important question. I'm thrilled you enjoy this recipe!
DeleteTo answer your question, you should be fine to use your milk that is 7-10 days beyond its best by date, as long as it's not opened. You can freeze your unopened milk if you have room in the freezer.
For best results, however, use the freshest ingredients you can find. Enjoy!π
